3. Due to the contact drying of hot air and raw materials, the raw materials are carbonized after drying, so the surface of the produced pellets will appear black. This kind of raw material will also lead to a decrease in pelletizing output and increase the wear on the ring die roller. If the compression ratio of the mold is too high, it can be reduced through JNSHARE's technology. Generally, the compression ratio of the pellet machine ring die provided by the manufacturer to the user is customized according to the commonly used raw materials. Since the raw materials and pelletizing processes used by various manufacturers are different, the selection standard of the compression ratio of the pellet machine ring die is not fixed. The specific and appropriate compression ratio depends on the optimal value that can be obtained by mastering and exploring during the production process.
